Property not found error in XAML

[LucaCris]

Describe the bug

The famous 8.x bug of the invalid property during editing now (8.2.1) seems to be present only for RelayCommand:

As you can see, other VM.XXX attributes are ok. No underlined errors neither in cs file.

So we should be almost there with the final fix...

I had the same. Deleting bin and obj and running a clean / rebuild would often fix it. for a few minutes. then after i edit or add a new relaycommand it would break again. It would build but intellisense would be confused. and sometimes it wouldnt build even if i didnt change anything. going all the way back to 8.0.0 for mvvm toolkit seems to work so far. looks like its a vs thing? https://github.com/dotnet/roslyn/issues/67123
